Humor is highly subjective. Take the list of funny books at the end of that article. "The long dark tea-time of the soul," was wretched in my humble opinion. Yet I couldn't stop laughing while reading "Dirk Gently's Holistic Detective Agency" (same author, same style, some of the same characters). I also tend to prefer children's literature because the authors tend to take a "laugh with" approach. I never understood why people think that laughing at others, particularly in difficult circumstances, is funny. Of course, the majority of adults would beg to differ. :/
